Description
Die Erfindung betrifft ein Verfahren und einen Jigger zum Färben von Textilbahnen aus Polyesterfasern (PES-Fasern) oder Gemischen von PES-Fasern mit anderen, natürlichen Fasern, insbesondere cellulosischen Fasern wie Baumwolle, aber auch Leinen, Wolle u.a., und synthetischen Fasern wie Viskosefasern u.ä., bei denen eine Warenbahn von einer Docke abgewickelt, durch ein Färbebad geleitet und nachfolgend zu einer Docke wieder aufgewickelt wird und sich dieser Vorgang jeweils durch Richtungsumkehr der Bahnbewegung wiederholt.The invention relates to a method and a jigger for dyeing textile webs made of polyester fibers (PES fibers) or mixtures of PES fibers with other natural fibers, especially cellulosic fibers such as cotton, but also linen, wool etc., and synthetic fibers such as Viscose fibers and the like, in which a web of material from a dock unwound, passed through a dye bath and subsequently to a dock is rewound and this process repeated by reversing the direction of the path movement.
Gegenüber anderen üblichen Textilfasern ist die Färbbarkeit von Polyesterfasern beträchtlich schlechter. Dies ist durch ihre geschlossene Struktur und ihren hohen Orientierungsgrad gegeben. Daraus folgen ein geringes Quellvermögen und hydrophobe Eigenschaften. Außerdem enthält die Polyesterfaser keine freien farbstoffbindenden Gruppen und besitzt nur eine geringe Affinität zu wasserlöslichen Farbstoffen.Dyeability compared to other common textile fibers of polyester fibers considerably worse. This is due to its closed structure and high degree of orientation given. This results in a low swelling capacity and hydrophobic properties. In addition, the Polyester fiber no free dye-binding groups and has only a low affinity for water-soluble dyes.
Bis auf einige Ausnahmen sind für die Polyesterfasern
nur Dispersionsfarben verwendbar, mit denen die Polyestertextilien
nach folgenden drei Grundverfahren gefärbt werden:
Das unter 3) genannte Thermosol-Verfahren ist wegen der vergleichsweise geringen Flottenaufnahme von etwa 35 % für das Färben von zu 100 % aus Polyesterfasern bestehenden Textilbahnen mit Nachteilen behaftet. Insbesondere läßt die Gleichmäßigkeit der Farbaufnahme zu wünschen übrig. Außerdem ist das Thermosol-Verfahren wie alle kontinuierlichen Verfahren ökonomisch nur für größere Färbepartien geeignet.The thermosol process mentioned under 3) is because of the comparatively low fleet absorption of about 35% for dyeing 100% polyester fibers Textile webs have disadvantages. In particular, the Uniformity of color picking left something to be desired. Furthermore is the thermosol process like all continuous processes economically only suitable for larger dyeing batches.
Das Färben mit Hilfe von Carriern gemäß 1) wurde vor allem in der ersten Phase der Einführung der Polyesterfasern in die Textilproduktion häufig ausgenutzt. Heute ist jedoch sein Anteil stark zurückgegangen. Die Carrier ermöglichen ein ausreichendes Quellen der PES-Fasern schon beim Temperaturen von 95°C und fördern so die Farbstoffdiffusion in die PES-Faser. Die Carrier sind jedoch meistens toxisch und ihr Einsatz ist nicht im Einklang mit dem Umweltschutz.The dyeing with the help of carriers according to 1) was before especially in the first phase of the introduction of polyester fibers often used in textile production. Today is however its share declined sharply. Enable the carriers sufficient swelling of the PES fibers even at temperatures of 95 ° C and thus promote dye diffusion into the PES fiber. However, the carriers are mostly toxic to you Use is not in line with environmental protection.
Als Auszieh-Färbeverfahren wird deshalb vorwiegend das HT-Färben von 120°C bis 130°C verwendet. Färben bei Temperaturen über 100°C ist jedoch nur auf Anlagen durchführbar, die für einen dem angeführten Temperaturbereich entsprechenden Überdruck konstruiert sind.This is why this is predominantly used as the exhaust dyeing process HT dyeing from 120 ° C to 130 ° C used. Coloring at temperatures However, over 100 ° C can only be carried out on systems those for a temperature range corresponding to the one mentioned Overpressure are constructed.
So ist es bekannt, für das Färben PES-Fasern mit Dispersionsfarbstoffen einen sogenannten HT-Jigger zu verwenden, der eine Färbetemperatur im Bereich von 120° C bis 130° C ermöglicht. Zu diesem Zweck muß das Gehäuse des Jiggers einem Dampfdruck zwischen etwa 2 und 5 Bar standhalten. Entsprechend aufwendig sind die Konstruktion und der Betrieb einer solchen Anlage.So it is known for dyeing PES fibers with disperse dyes to use a so-called HT jigger which has a dyeing temperature in the range of 120 ° C to 130 ° C enables. For this purpose the housing of the jigger withstand a steam pressure between about 2 and 5 bar. The construction and operation are correspondingly complex such a facility.
Die dem Oberbegriff zugrundeliegende FR-A-1 333 808 zeigt einen Jigger u.a. zum Färben von Polyester, bei welchem auf die Warenbahn vor dem Aufwickeln auf einen der Wickel von beiden Seiten Dampf aufgesprüht wird, der über die Bahnoberfläche hinwegstreichen soll. Nach dem Aufbringen des Dampfes und vor dem Auflaufen auf den Wickel passiert die Warenbahn eine Leitrollen-Breithalter-Kombination. Es hat sich gezeigt, daß die temperatursteigernde und färbungsfördernde Wirkung dieser Anordnung verbesserungswürdig ist. FR-A-1 333 808 on which the generic term is based shows a jigger etc. for dyeing polyester, in which onto the web before winding onto one of the rolls of steam is sprayed on both sides over the surface of the web should sweep away. After applying the steam and before it hits the roll, the web passes a guide roller-spreader combination. It has shown, that the temperature-increasing and coloring-promoting effect this arrangement is in need of improvement.
Davon ausgehend liegt der Erfindung die Aufgabe zugrunde, das Färben von Textilbahnen aus Polyester und seinen Gemischen zu verbessern.Proceeding from this, the object of the invention is the dyeing of textile webs from polyester and its To improve mixtures.
Zur Lösung dieser Aufgabe wird ein Verfahren mit den Merkmalen des Anspruchs 1 vorgeschlagen.To solve this problem, a method with the Features of claim 1 proposed.
Ein ausschlaggebender Faktor für das Färben von PES ist die Färbetemperatur. In drucklosen (atmosphärischen) Färbemaschinen kann höchstens die Kochtemperatur der Flotte erreicht werden, die bekanntlich von der Höhe des Standorts über dem Meer abhängig ist. Bei einer Höhe ü.M. von etwa 300 m liegt die maximale erreichbare Temperatur in geschlossenen Färbegefäßen bei etwa 98°C bis 99°C, und zwar unter Voraussetzung einer perfekten Abdichtung des Haubenraumes des Jiggers.A key factor in staining PES is the dyeing temperature. In pressureless (atmospheric) dyeing machines can at most reach the cooking temperature of the fleet that are known to depend on the height of the location is dependent on the sea. At a height above sea level of about 300 m is the maximum achievable temperature in closed Dyeing vessels at about 98 ° C to 99 ° C, provided that a perfect seal of the hood space of the Jiggers.
Bei der Erfindung wird die Textilbahn nach ihrem Austreten aus dem auf Siedetemperatur oder unmittelbar unterhalb der Siedetemperatur sich befindenden Färbebad durch Zuführen von Wärmeenergie unmittelbar in den Aufwickelspalt und durch Nutzung der Kondensationswärme auf Sattdampftemperatur von 100°C gebracht und unter diesen Betriebsbedingungen aufgedockt - die erreichte Temperatur wird also sozusagen "eingewickelt" und kommt dem Aufziehvorgang zugute. Schon ein Temperaturge-winn von nur wenigen Grad führt zu einer merklichen Erhöhung der Farbstoffausbeute von mehreren Prozent. Es wird durch die erfindungsgemäße Maßnahme die äußerste unter Atmosphärendruck mögliche Temperaturerhöhung sichergestellt und zur Verbesserung des Verfahrensergebnisses genutzt. Die Erfindung gestattet es, Polyesterfasern umfassende Textilbahnen bei guter Farbtiefe und Farbechtheit in einer vergleichsweise einfachen, keine druckfesten Gehäuse benötigenden Vorrichtung und unter vergleichsweise geringem Energieeinsatz zu färben, ohne daß eine hohe Anzahl der Durchgänge der Ware durch das Färbebad erforderlich sind.In the invention, the textile web is after it emerges from the boiling point or immediately below the boiling temperature of the dye bath Supply of thermal energy directly into the winding nip and by using the heat of condensation to saturated steam temperature of 100 ° C brought and docked under these operating conditions - the temperature reached is "wrapped up", so to speak and benefits from the winding process. Already a temperature gain of only a few degrees leads to a noticeable increase the dye yield of several percent. It is through the measure according to the invention is the most extreme under atmospheric pressure possible temperature increase ensured and for Improvement of the process result used. The invention allows textile webs comprising polyester fibers with good color depth and color fastness in a comparative simple, no pressure-resistant housing required Device and with comparatively low energy consumption to color without a large number of passes of the Goods through the dye bath are required.
Der durch die Erfindung erzielbare Färberfolg wird
durch eine geeignete Fabstoffauswahl gesteigert. Es werden
solche Dispersionsfarbstoffe ausgewählt, die unter den angeführten
Bedingungen, d.h. bei Temperaturen von etwa 100°C, in
die Polyesterfaser diffundieren und dieselbe färben. Die
Auswahl wird außerdem durch Erfüllung folgender Kriterien
bestimmt:
Als in diesem Sinn besonders vorteilhaft für das Färben von Textilbahnen aus PES-Fasern nach dem erfindungsgemäßen Verfahren haben sich die folgenden Farbstofftypen aus der Gruppe der Dispersionsfarbstoffe erwiesen (Anspruch 2):
- Colour Index Disperse Yellow 3
wie z.B. Cellitongelb G (BASF) - Colour Index Disperse Yellow 60
wie z.B. Resolingelb RL (Bayer) - Colour Index Disperse Yellow 68
wie z.B. Samarongoldgelb HGL (Hoechst) - Colour Index Disperse Orange 3
wie z.B. Cellitonorgange GR (BASF) - Colour Index Disperse Red 1
wie z.B. Cibacetscharlach 2B (Ciba-Geigy) - Colour Index Disperse Red 50
wie z.B. Resolinscharlach RR (Bayer) - Colour Index Disperse Violet 1
wie z.B. Cibacetviolett 2R (Ciba-Geigy) - Colour Index Disperse Blue 81
wie z.B. Resolinblau GRL (Bayer)
- Color Index Disperse Yellow 3
such as Cellitongelb G (BASF) - Color Index Disperse Yellow 60
such as resol yellow RL (Bayer) - Color Index Disperse Yellow 68
such as Samarong golden yellow HGL (Hoechst) - Color Index Disperse Orange 3
such as Celliton Organ GR (BASF) - Color Index Disperse Red 1
such as Cibacetscharlach 2B (Ciba-Geigy) - Color Index Disperse Red 50
such as Resolin scarlet RR (Bayer) - Color Index Disperse Violet 1
such as Cibacet violet 2R (Ciba-Geigy) - Color Index Disperse Blue 81
such as Resolin Blue GRL (Bayer)
Diese Farbstoffe sind im weitesten Sinne "kleinmolekulare" Dispersionsfarbstoffe, also "Low energy" Typen mit hohem Migrationsvermögen, d.h. Farbstoffe, die eine geringe Energie für das Eindringen in die Faser benötigen, sowie akzeptabler Sublimierechtheit. Dies gilt - mit gewissen Einschränkungen - auch für "mittelmolekulare" Dispersionsfarbstoffe, die "medium energy" Typen mit ausreichendem Migrationsvermögen sowie sehr guter Sublimierechtheit. Großmolekulare Dispersionsfarbstoffe oder "high energy" Typen mit geringem Migrationsvermögen und maximaler Sublimierechtheit erweisen sich in der Regel als weniger bis nicht geeignet.In the broadest sense, these dyes are "small-molecular" Disperse dyes, ie "low energy" types with high migration capacity, i.e. Dyes that are low Need energy for penetration into the fiber, as well acceptable sublimation fastness. This applies - with certain Restrictions - also for "medium molecular" disperse dyes, the "medium energy" types with sufficient Migration ability and very good fastness to sublimation. Large molecules Disperse dyes or "high energy" types with low migration capacity and maximum sublimation fastness usually turn out to be less or not suitable.
Die genannten Dispersionsfarbstoffe erfüllen die vorstehend erwähnten Kriterien. Mit diesen Farbstoffen sind auch Trichromien in dem erforderlichen Umfang möglich. Außerdem wird eine ausreichende Sublimierechtheit gewährleistet. Besonders bei den genannten Farbstofftypen werden im Zusammenwirken mit der zusätzlichen Aufheizung, also bei höheren Färbetemperaturen, bessere Färbeergebnisse erzielt.The disperse dyes mentioned meet the above mentioned criteria. With these dyes Trichromas are also possible to the extent necessary. Furthermore sufficient sublimation fastness is guaranteed. Especially with the mentioned types of dyes Interact with the additional heating, that is higher dyeing temperatures, better dyeing results.
Ein wichtiger weiterer Einflußfaktor zur Verbesserung des Färbeergebnisses bei dem erfindungsgemäßen Verfahren ist das Flottenverhältnis bzw. das Konzentrationsgefälle. Das Konzentrationsgefälle beeinflußt die Farbstoffdiffusion in die Faser.Another important factor for improvement of the coloring result in the method according to the invention the liquor ratio or the concentration gradient. The Concentration gradient affects dye diffusion in the fiber.
Gemäß Anspruch 3 sollte im Bereich der Flottenverhältnisse von 1 : 1,3 bis 1 : 2,5 gefärbt werden. Daraus ergibt sich eine Verdoppelung der Farbstoffkonzentration in der Färbeflotte gegenüber den herkömmlichen Jiggern. Dieser Faktor beteiligt sich auch sehr deutlich an der Farbstoffausbeute.According to claim 3 should in the area of the fleet from 1: 1.3 to 1: 2.5. It follows a doubling of the dye concentration in the Dyeing liquor compared to conventional jiggers. This Faktor also participates very clearly in the dye yield.
Eine vorteilhafte Ausgestaltung des Verfahrens besteht in der Zugabe eines das Flottentragevermögen erhöhenden Film-bildners (Anspruch 4), z. B. auf der Basis von Acrylamidpolymeren (Anspruch 5).There is an advantageous embodiment of the method in the addition of a film-forming agent which increases the floatability (Claim 4), e.g. B. on the basis of acrylamide polymers (Claim 5).
Anspruch 6 und 7 geben den apparativen Aspekt der Erfindung wieder.Claims 6 and 7 give the apparatus aspect of the invention again.
Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der Zeichnung eines 2-Becken-Jiggers näher erläutert, die eine perspektivische, zum Teil aufgebrochene und schematisierte Darstellung eines in seinen Grundelementen bekannten Jiggers erkennen läßt. An embodiment of the invention is as follows based on the drawing of a 2-tank jigger explained, which is a perspective, partially broken and schematic representation of one in its basic elements known jiggers.
Der Jigger umfaßt in einem Gehäuse 10 zwei Wickelwalzen
21,22, zwischen denen eine Textilbahn 1 aus PES-Fasern hin-
und hergewickelt wird und zwischen denen zwei kleine im
Wechsel oder im gleichen Durchlauf nacheinander einsetzbare
Becken 11 und 12 sowie dazwischen ein höhenverstellbares
Breitstreck-Streichrohr 13 angeordnet sind. Ferner sind mit
einstellbarer Kraft gegen die Wickelwalzen 21 und 22 anpreßbare
Andrückwalzen 14, 15 vorgesehen, die eine saubere Wikkelausbildung
unterstützen sollen. Das Gehäuse 10 ist in
geeigneter Weise gegen das Eindringen von bzw. den Austausch
mit Außenluft wirkungsvoll abgedichtet. Es weist für den
Partienwechsel eine verschwenkbare Zutrittsluke 16 auf.The jigger comprises two winding rollers in a
Mittels einer Steuerungs- und Regeleinheit 17 sowie
zugehörigen und in der Zeichnung nicht eigens dargestellten
Temperaturfühlern werden die Färbeflotten 2, 3 in den Becken
11,12 unter Zuhilfenahme von Heizregistern 4 auf eine solche
Temperatur eingeregelt, die gleich oder nur geringfügig, z.
B. 1° C, kleiner als die Siedetemperatur der Färbeflotten
unter den herrschenden atmosphärischen Druckbedingungen ist.By means of a control and regulating
Im Raum oberhalb der Färbebecken 11 und 12, von denen
auch nur ein einziges verwendet werden kann, sind entlang
ihrer Längserstreckung mit Düsen versehene, Sattdampf führende
Dampfsprüh-Rohre 18, 19 derart angeordnet, daß im
Bereich der Wickelwalze, auf die die Textilbahn 1 aus PES-Fasern
gerade aufgedockt wird (in der Zeichnung ist dies die
Wickelwalze 22) die Textilbahn 1 über die gesamte Bahnbreite
mit Sattdampf 24 bedüst wird. Die Dampfsprüh-Rohre 18 sind
unmittelbar vor der Auflaufstelle der Textilbahn 1 auf den
Wickel angeordnet und wirken in dem Aufwickel spalt gegen die beim Aufwickeln dem
Wickel zugewandten Seite der Textilbahn 1, so daß diese mit
der erreichten Temperatursteigerung um einige Grad sogleich
auf den Wickel aufläuft. Die Dampfsprüh-Rohre 19 wirken
gegen den Außenumfang des Wickels. Mit dieser Bedüsung wird
die Temperatur zumindest in der der Docke zulaufenden Zone
der Textilbahn 1 sowie am Umfang der Docke auf Sattdampftemperatur
gesteigert. In the room above the
Als von erheblichem Vorteil hat sich der Zusatz von sogenannten Filmbildnern zur Färbeflotte für PES-Fasern in den Becken 11,12 erwiesen. Durch Zusatz filmbildender Mittel auf der Basis von Acrylamidpolymeren konnte die Flottenaufnahme um 10 % erhöht werden. Die größere Flottenmenge wirkte sich innerhalb des Warenwickels als besonders vorteilhaft aus, weil das Farbstoffangebot während der Verweilzeit auf der Docke höher war und die Farbstoffdiffusion beschleunigt wurde. Außerdem wurde eine bessere Egalität der Färbung festgestellt. Bereits 3 bis 5 g eines Filmbildners auf der Basis von Acrylamidpolymeren pro Liter Färbeflotte reichte hierfür aus.The addition of. Has proved to be of considerable advantage So-called film formers for dyeing liquor for PES fibers in proved the basin 11.12. By adding film-forming agents on the basis of acrylamide polymers, the liquor intake be increased by 10%. The larger amount of the fleet worked itself as particularly advantageous within the product winding out because the dye supply on during the dwell time the dock was higher and the dye diffusion accelerated has been. It also improved the levelness of the coloring detected. Already 3 to 5 g of a film former on the The basis of acrylamide polymers per liter of dye liquor was sufficient for this.
Auf dem beschriebenen Jigger wurden folgende Färbeversuche gefahren:The following dyeing tests were carried out on the described jigger hazards:
